At that level you're talking about framework api's (in this case NextStep and derivatives), not the language itself. Drop me into some Haskell or Java or OCaml

At that level you're talking about framework api's (in this case NextStep and derivatives), not the language itself. Drop me into some Haskell or Java or OCaml or Python or Ruby framework, I'm going to have to reach for a reference as well. It's not uncommon to conflate Objective-C conversationally with its most common use case, but Objective-C is not NextStep and other Apple-ecosystem friends.
